In this example, we are giving a program to find the factorial of a number.

Program to find a factorial number:

  1. def  factorial(n):
  2.   # Single line to find factorial
  3.   return  1 if (n==1 or n==0) else n * factorial(n - 1);
  4. num = 5
  5. print("Factorial of",num,"is"
  6.     factorial(num))
